I want to solve both of these equations by graphing.
00:03
I want to do that, i'm going to turn them into y equals mx plus b form.
00:08
So that's going to be slope and y intercept.
00:11
So for the first case, i'm actually going to bring the seven over this way.
00:14
So then i rewrite this in a different order.
00:16
So it looks like this.
00:17
3y is equal to 4x minus 7.
00:20
From there, i need to divide everything by 3.
00:24
And that's going to give 4 thirds x minus 7 thirds.
00:28
So that's into y equals mx plus b form.
00:31
For this one, we'll bring the 8x over to this side.
00:34
So it's a negative 6y is equal to a negative 8x plus 14.
00:39
Then divide everything by a negative 6.
00:42
So negative 8 over negative 6 is going to become positive and reduces to 4 over 3.
00:47
14 over negative is going to be negative and that's going to reduce to 7 over 3.
00:53
So from here, my y intercept is negative 7 thirds and positive 4 thirds for the slope.
00:59
So i crossed that at negative, be 2...
